- This patch enables lpm for ARM
- Used architecture agnostic xmm_t to represent 128 bit SIMD variable in
rte_lpm_lookupx4 API definition
- Tested on Juno and Thunderx boards
- Tested and verified the changes with following DPDK unit test cases
--lpm_autotest
--lpm6_autotest
v1..v2
- make rte_lpm_lookupx4 API definition architecture agnostic
- vect_* abstraction scope reduce to only app/test as this abstraction used
only to load/store and set vectors in test application which is
the consumer of rte_lpm_lookupx4 like API
- support for armv7 apart from armv8
- taken changes from Jianbo's lpm patches
v2..v3
- add Acked-by for
0001-lpm-make-rte_lpm_lookupx4-API-definition-architectur.patch
- re-based to DPDK 2.2
-- fixed the conflict in config/defconfig_arm-armv7a-linuxapp-gcc and
MAINTAINERS file
v3..v4
-Instead of defaulting the lpm implementation to SSE, SSE implementation
kept under RTE_ARCH_X86 conditional compilation check as suggested by Thomas
Jerin Jacob (3):
lpm: make rte_lpm_lookupx4 API definition architecture agnostic
lpm: add support for NEON
maintainers: claim responsibility for arm64 specific files of hash and
lpm
